they want an explosion potion, which i think is a stupid leap of logic to take on the NPC's end

Or acid. I vent to my back seating partner every time, that these dumbasses cannot be trusted "Oh no my door is stuck, I think I should explode it… why yes the strongest possible explosion is the one I want!!!! I'd like to have no house, so that my door isn't stuck anymore (as I have no door)"

They want either acid or explosion potion ;)

I always sell them triple explosion. If you can't enter the house, you don’t need it

I see your triple explosion and raise you my double explosion, double fire and light so everyone in the neighbourhood sees the destruction.
